Superstring Scattering from D-Branes
Mohammad R. Garousi, Robert C. Myers
We derive fully covariant expressions for all two-point scattering amplitudes of two massless closed strings from a Dirichlet -brane. This construction relies on the observation…

Conformally invariant off-shell string physics
Robert C. Myers, Vipul Periwal
Using recent advances in the understanding of non-critical strings, we construct a unique, conformally invariant continuation to off-shell momenta of Polyakov amplitudes in critica…

What unitary matrix models are not?
Rene Lafrance, Robert Myers
We report results of two investigations of the double-scaling equations for the unitary matrix models. First, the fixed area partition functions have all positive coefficients only…
